Low Oxygen levels
I just set up a 24 gallon aquapod, transferring the water from an established 10 gallon tank and a percula clown. This morning the fish looked distressed (gasping) and was not eating (a first for the clown). The salinity in this tank is 1.024, with ammonia, nitrite and nitrite is 0. I also checked the Oxygen level and found that it was 2 mg/l, which is the lowest on the scale. By comparison, my 29 gallon biocube is at 6mg/l.
Not knowing what else to do, I put in an air stone in the tank, hoping to raise the oxygen level. But I've read that micro bubbles can also harm saltwater fish. None of my other tanks require an air pump/stone. Does someone understand this? Is there something else I should be doing to keep 02 levels without the use of an air pump?
